On the behavior of the nondimensional wind shear in an urban roughness sublayer
Christoph A. Vogel, NOAA/OAR/ARL/ATDD, Oak Ridge, TN; and W. Pendergrass
As part of the NOAA DCNet study, a mini Doppler Sodar was deployed for a number of months on a rooftop in downtown Washington, DC. Numerous wind profiles were measured up to approximately 6 canopy heights. These profiles allowed for determinations of the height of the roughness sublayer (RSL), and for investigations into the nondimensional wind shear within the RSL in near-neutral conditions. A relation for the behavior of the nondimensional wind shear is presented.
